Tubular linear motors can achieve high levels of precision due to their direct drive design, which eliminates backlash, compliance, and wear associated with mechanical transmission systems. This results in improved positioning accuracy and repeatability.

Fast Dynamic Response
These motors exhibit excellent dynamic performance with fast acceleration and deceleration capabilities, allowing them to quickly respond to changes in demand, making them ideal for applications requiring rapid movement and precise control.

Low Maintenance
With no intermediate mechanical components, tubular linear motors have fewer parts that can wear out or require maintenance, leading to lower overall maintenance costs and increased reliability.

Compact Design
The cylindrical design of tubular linear motors enables a smaller footprint and reduced weight compared to other linear motor technologies. This allows for greater design flexibility and easier integration into existing systems.

Application of AC Tubular Motor

Roller Shutters and Blinds

AC tubular motors are widely used in the automation of roller shutters and blinds. They provide a convenient and efficient way to control the opening and closing of these window coverings.

Awning Systems

Tubular motors are employed in retractable awning systems for homes, commercial spaces, and outdoor areas. They enable easy extension and retraction of awnings, offering sun protection and shade control.

Projection Screens

AC tubular motors are used in motorized projection screens. This application allows for automated rolling and unrolling of projection screens in home theaters, conference rooms, or other presentation spaces.

Garage Doors

Tubular motors are utilized in automated garage door systems, providing a reliable and convenient method for opening and closing garage doors.

Curtain Automation

In both residential and commercial settings, AC tubular motors are applied to automate curtains. This allows for remote or automated control of curtain movement.

Greenhouse Ventilation

Tubular motors can be used in greenhouse systems to automate the opening and closing of ventilation windows. This helps regulate temperature and humidity levels for optimal plant growth.

Working Principle of AC Tubular Motor

A tubular linear motor is a type of direct drive linear motor, which means it directly converts electrical energy into linear motion without the need for intermediate mechanical components like gearboxes, belts, or screws. It consists of two main components: the stator (stationary part) and the mover (moving part). The stator contains a series of coils arranged in a cylindrical shape, while the mover has permanent magnets embedded in a cylindrical steel tube. When an alternating current is applied to the stator’s coils, it generates a magnetic field that interacts with the permanent magnets in the mover, producing linear motion. By controlling the current waveform, the motor’s position, speed, and acceleration can be precisely controlled, enabling high-performance linear motion systems.

Maintenance Tips for AC Tubular Motor

You should regularly inspect your motor mount. Damage to the motor mount can quickly result in problems for the entire motor assembly. Pay attention to ensure that all mounting bolts are tight and secure, with no obvious play present. Any cracked plates you find should be replaced.

Examine the rotor and stator. You’ll want to make sure that the gap between these components remains at an optimal distance. Any changes you notice from prior measurements are an indication that the motor bearings may need to be replaced. You should also blow out the motor regularly to keep everything clean and free-flowing.

Don’t over do the lubrication. You absolutely need to keep the motor properly lubricated, but many people tend to overdo it. Using too much lubricant can cause oil to get trapped in the windings, thus leading to premature deterioration of motor components. Be sure to follow the manufacturer’s guidelines for lubrication amounts and frequency.

Don’t neglect to keep good service records. Maintaining accurate records about the status of your AC motor, as well as about what service has been applied, is essential for the long-term operating life of your equipment. Keeping good records makes it easier to identify any recurring issues that may call for specific part replacements.

Ultimate FAQ Guide to AC Tubular Motors

Q: What is the function of AC Tubular Motor?

A: The tubular motor can offer extensive range and value for money and can also provide effective performance along with quality and reliability. They are used for various applications for the interior (blinds/curtain covering), external (awnings), roller shutters, etc.

Q: How does a tube motor work?

A: A tubular linear motor is a type of linear electric motor with a forcer consisting of a series of solenoids wrapped around a cylinder enclosing a movable rod that contains a number of strong cylindrical permanent magnets aligned in alternating and opposing directions.

Q: What are the benefits of cylindrical design?

A: Tubular linear motors consist of a thrust rod (or tube) with permanent magnets and a stator (sometimes referred to as a forcer) with coils. The most common configuration is a fixed thrust rod with a moving stator, to which the load or tooling can be attached. But some manufacturers offer configurations in which the rod extends and retracts from a housing that encloses the stator. This design provides an alternative to pneumatic or screw-driven rod-type actuators. In rod-style thrust applications, linear motors provide high speed and acceleration, the ability to withstand high duty cycles, and precise positioning.
The primary benefit of tubular linear motors over flat and U-channel types is their high efficiency. Linear motors work on the principle of the Lorentz Force, which states that when a conductor with current (the stator) is placed in a magnetic field that is perpendicular to the current, a force is generated on the conductor. The direction of the force is perpendicular to both the magnetic field and the current. The key for tubular linear motors is that their design allows the entire coil (not just a portion of the coil, as in flat and U-channel designs) to be perpendicular to the magnetic flux, so all of the current is used to generate force in the direction of travel, maximizing their efficiency.
High efficiency devices generate less heat, so less cooling is needed. Less heat also means less expansion and contraction of components due to thermal effects, and more importantly, less heat transferred to the external load or work environment. The result is better positioning accuracy, which is especially important for cutting, machining, or dispensing applications. Although some designs are available with iron core stators for higher force production, most tubular motors are ironless, so they have no cogging effects and produce very smooth motion.

Q: What is the working principle of the tubular motor?

A: The stroke part is the motor part that controls the upper and lower limit of the motor. The deceleration part responsible for the operation of the motor mostly uses planetary deceleration, which has the effect of reducing the motor speed and increasing the output torque.

Q: According to the operation principle of the stroke part during power failure, how many categories can tubular motor be divided into?

A: According to the operation principle of the stroke part during power failure: standard tubular motor, handle tubular motor, chain tubular motor, clutch tubular motor, resistance tubular motor, etc.

Q: What should we pay attention to during maintenance of tubular motor?

A: WARNING – Disconnect the power supply to the operator before servicing.
● Inspect and service whenever a malfunction of either door or operator is observed or suspected.
● Before servicing, always disconnect the power supply to the operator.
● All replacement parts must be compatible with those originally provided.
● If an entrapment protection device is used, i.e. sensing edge, please consult the manufacturer for maintenance instructions.

Q: What are the pros and cons of AC vs DC motors?

A: AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

Q: Can AC tubular motor be used in sunshade systems?

A: Yes. Tubular motors can be used in greenhouse systems to automate the opening and closing of ventilation windows. This helps regulate temperature and humidity levels for optimal plant growth.

Q: Can AC tubular motor be used in smart home systems?

A: Yes. With the rise of smart home technology, AC tubular motors are integrated into home automation systems. This allows users to control various motorized applications remotely through smart devices.

Q: What does an AC tubular motor consist of?

A: High-quality components such as motors, trolley bodies, windings, bearings, and brushes are used during the manufacturing process of tubular motors for rolling shutters. The testing procedures are performed at all points of the product lifecycle to ensure that the product meets high-quality standards. All components are subjected to temperature ranges and pressures to test their ability to bear the impact of extreme weather conditions and adverse conditions. All the tests are carried out in a controlled environment to ensure the best quality.

Q: What is the operating principle of AC tubular motor?

A: AC motors have two main principles of operation: different speeds and different torque. They work on the principle of the rotation of a circuit from high voltage, low amperage to a low voltage, high amperage. AC motors first create a rotating magnetic field with an AC that is switched on and off at a constant frequency. So if the resulting magnetic field rotates clockwise, then applying a DC in one direction will cause clockwise rotation as well as attraction forces to other nearby magnets or ferrous materials such as iron cores or steel laminations. In contrast, reversing this polarity by switching on the same magnitude DC in the opposite direction will reverse both rotation and attraction force directions from those before reversal. The brushing motors of the past would wear out quickly because their brushes would constantly contact parts of the armature with high voltage. Therefore, synchronous motors were developed. Synchronous motors are induction motors that operate on a single-phase power source – hence their name “single-pole, single-phase” (1P1). Synchronously operating induction motors have two poles on shafts surrounded by stationary magnets. The electrical current alternates between these poles. AC Motor is that the rotation of the motor is caused by alternating electric current traveling through the coils. The direction of this current flows changes at a specific frequency. This speed can be determined using a copper wire that creates a magnetic field when energized by electrical pulses, and it travels through the wires in one direction until reversing course to travel in the opposite direction back to its starting point. When moving in one direction, electrons flow away from it towards another coil, inducing an electric charge or voltage on its core’s two windings which turns out to be what causes electromagnetic induction within each coil when it reaches Faraday’s law.

Q: What factors will affect the service life of AC tubular motor?

A: Type of Motor
Different motor types have different lifespans. For example, small DC motors used in appliances may last from two to five years, while large industrial AC motors can last decades with proper care.
Usage
How much and how hard the motor is used significantly impacts its lifespan. The constant heavy-duty operation will naturally shorten its life compared to light, infrequent use.
Operating Conditions
Environmental factors -- such as temperature, humidity, dust and vibration -- also play a big role in the motor's lifespan, and harsh conditions can lead to faster wear and tear of its components.
Maintenance Plan
Regular maintenance activities -- such as lubrication, cleaning and bearing checks -- can extend the motor's lifespan, because you can usually detect potential problems early on.

Q: Are tubular motors easy to install?

A: Tubular motors are simple to install and commission. Optimally matched accessories such as latching couplings, pluggable cables, and motor bearings with a click system additionally facilitate the installation.

Q: Can a tubular motor be controlled remotely?

A: You can rotate a tubular motor in the positive or reversal direction with the transmitter (remote control) from any place within a reliable distance. The RF wireless signal can pass through walls, floors and doors.

Q: How do you adjust the speed of a motor?

A: We can see that the angular velocity, (AKA motor speed, AKA RPM), is proportional to voltage and negatively proportional to torque. Therefore, if we want to increase the motor's speed we can either a) increase the voltage delivered or b) decrease the torque.

Q: How to change the RPM of a motor?

A: As an electric motor does not have RPM (revolutions per minute) adjustments like a combustion engine, you can typically change the speed of an electric motor by adjusting the input voltage, changing the frequency of the power supply, or using a variable frequency drive (VFD) or motor controller.

Q: What are the main applications of AC tubular motors?

A: AC tubular motors are commonly used in roller shutters, blinds, awnings, garage doors, curtain automation, and more.

Q: Can AC tubular motors be used outdoors?

A: Yes, many AC tubular motors are designed to withstand outdoor conditions, making them suitable for awnings, sunshades, and more.

Q: Can I integrate AC tubular motors with smart home systems?

A: Yes, you can also integrate mechanical tubular motors into the smart home system, so you can: Control the connected motors individually, in groups or in scenarios. Control consumption and manage electrical loads, thus reducing energy waste.

Q: Do tubular motors support different tube sizes?

A: Yes. Our standard tubular motor and adapter designs allow you to easily motorize and automate virtually any type of window covering. Motors are available in a wide range of drive and crown sizes to support different tube diameters and window sizes.

Q: Are tubular motors noisy during operation?

A: No, these motors are designed for quiet operation, providing a smooth and noise-free experience.

Q: What are the characteristics of AC tubular motor?

A: First, tubular motors for roller blinds are made of steel pipes. Tubes of this material are usually available in standard sizes. The larger the tube size, the larger the motor size. Tubular electric motors are also known as winding or tubular generators. Tubular motors for roller blinds are mainly designed for outdoor applications and have unique characteristics. It is designed in such a way that it can be folded or compressed in any way without compromising its functionality. For such applications, the application must be portable. In other words, it should have less weight and more torque. In other words, the strength of such a motor is directly proportional to its weight. The heavier the weight, the more torque and vice versa.
